“Uh, excuse me. Princess Twilight, Princess Luna, what are you doing?” Luna looked up from her task, and toward the pony who was asking the question. Raising her head even further, she showed her toothbrush, and gave a toothy smile.

“We are cleaning up the world. It is a very dirty place, and thus we must clean it. Sweetie Belle! I require more toothpaste!” Luna shouted the last bit of her sentence as, brandishing her toothbrush, she glanced toward the white filly currently squirting toothpaste into buckets. Raising her head, she gave a toothy grin.

“Of course, remember, we’re getting to the root of the problem.” Sweetie levitated over a bucket filled with toothpaste, and Luna smiled, getting back to work. Twilight scrubbed beside her.

“Uh, should we help?” The civilian glanced to the crowd behind him, and they all shared aversive glances. Luna raised her head and looked at them, startling the crowd.

“If you decide to leave, it's your floss, not mine.” Luna lent back down, and continued working. After a moment, the crowd decided to follow the lead of the Princesses. Walking over to Sweetie Belle, they asked to help.

“Remember to be kind to Luna too, she has fillings too.” Sweetie smiled, giving each pony a bucket of toothpaste. Stepping back, she watched as every pony went to work, scrubbing the ground.

‘Darn it, I’ve run out of puns’ Sweetie silently cursed that fact, and quickly got back to work putting toothpaste into buckets. Grinning when she wasn’t being watched, Sweetie felt immense pleasure at the fact most of Ponyville was now helping. It was amazing, watching all those ponies just work away, ‘cleaning’ the dirt.

“I’m out, this is the last bucket.” Sweetie levitated the bucket over, and Twilight stood up. Luna was quick to follow, and they both shared a glance, and then sighed, letting a sad look go over their eyes.

“It looks like we failed our mission,” sighed Luna, and both hugged each other. Sweetie bit her lip, forcing herself not to laugh as everypony glanced toward them. Standing up, it was the first stallion who spoke.

“Don’t worry! We’ll buy more toothpaste!” He spoke, raising his voice and looking to the crowd, daring them to deny him.

“And bleach!” A mare spoke up, standing up as well.

“And Soap!” The entire crowd stood up, now on a mission of great importance.

Sweetie watched as the crowd dispersed the moment Luna smiled, and they quickly vacated to the inside of the castle, saying they needed to rest. Taking a spot on the balcony, all three broke out into quiet laughter.

“How are things going in Canterlot?” Sweetie glanced to Luna, who snickered and let her horn glow, shimmering into some sort of mirror that began to reflect Canterlot. Sweetie blinked, and then fell to the floor, rolling in laughter.

“I’ll be, pff, honest. I didn’t expect-haha- Celestia to be behind the idea-tehehee.” Sweetie chortled as quietly as she could as Luna and Twilight smiled to the crowd below. The entire town was beginning to mobilise, just as they were doing in Canterlot. It wouldn’t be long until the Pegasi got involved to a greater degree.

“I will admit, I did not think this would take hold, but it’s spreading like wildfire. I am surprised by how much influence we have.” Luna waved to the crowd as she watched, and Twilight smiled warmly. Sweetie finally got control of her fit of giggled, and stood up, sneaking over to the edge.

“How’s Rarity doing in Manehattan?” Sweetie glanced upward, and both smiled, trying to hold in their grins. Sweetie couldn’t help but rub her hooves together, this was going extremely well. When she had told the Princesses, they had literally jumped at the chance, and the result was what was happening right now. Sweetie was amazed by how much influence a Princess had.

“Her influence is really helping. People are convinced she’s doing it to show of a line of fashion, and she is even making clothes for free to those who volunteer to help.” Twilight held up the letter from Rarity she had received, and Sweetie giggled. It had toothpaste stains all over it, some in the shape of hearts. Rarity was getting into the spirit of things.

“And what about Rainbow Dash and Applejack?” Sweetie wondered if the Apple family had enough influence in Appleoosa to complete the task, but soon realised she was worried for nothing. Twilight held up a picture of the buffalo helping to scrub the apple trees. Twilight then pointed toward the sky, where a large group of Pegasi were flying toward Ponyville.

“Rainbow Dash has a lot of influence there, especially with Celestia backing her. This is turning into an Equestrian-wide event. I heard Las Pegasus got wind of it and is doing the same thing.” Twilight couldn’t hold it in anymore, and she broke down into laughter. Sweetie couldn’t help it either, this was awesome.

And so, it was henceforth known as Toothpaste Day. Every year, on this day, everypony must spend half the day scrubbing the ground with a cleaning utensil to show their devotion to a clean Equestria. Some will decorate their houses with floss and toilet paper, enlisting the help of young colts who are practicing for Nightmare Night.

Celestia and Luna praised Equestria for proving their devotion to a clean society, and promised that Equestria was going to have another year of prosperity. This has led the event to also be known as Prosperity Day to the public. However, those who witnessed the events first moments still call it Toothpaste Day.

Eventually, it was decided that the festivities for next year’s Prosperity Day wouldn’t start until three ponies has started the scrubbing. These three ponies would be one of each race, and a Princess would be required to oversee the beginning of the event. Everypony cheered, for a new holiday had been created, and set in stone.

All before the Friday rolled around.
